For the past few months, I have this on and off feeling in my throat. It feels like someone is choking me or that my esophagus is contracting and won't let up. I finally went to my PCP's today and they are sending me to a GI specialist. She mentioned something about Barrett's Esophagus.. I freaked out and googled it. I have health anxiety problems and am now worried I have esophagus cancer.. Any ideas? I'm freaking out. I can't haven't a scope done until June. Should I go to the ER to get checked?
